Bioaccumulation versus adsorption of reactive dye by immobilized growing Aspergillus fumigatus beads

Single and binary dye and heavy metal bioaccumulation properties of Candida tropicalis: Use of response surface methodology (RSM) for the estimation of removal yields

“…Some of these techniques have been shown to be effective, although they have limitations [3,4]. Biological processes such as biosorption [5] and bioaccumulation [6][7][8][9][10][11][12][13][14] have been proposed as potential methods for the removal of dyes and heavy metals from textile wastewaters. Removal of pollutants by actively growing cells by metabolism-and temperature-independent and metabolismdependent mechanism steps is defined as bioaccumulation.…”

“…However, the fact that many conventional sewage treatment processes are based on living microbes suggests that such limitation would not prevent their applications in the bioremoval of pollutants. If the problem of pollutant toxicity to the growing cells is overcome by the use of pollutant-resistant organisms the continually self-replenishing system can be left to run continuously for extended periods [6][7][8][9][10][11][12][13][14]. Compared to bacteria and filamentous fungi, yeasts exhibit attractive features.…”

Decolorization pathways of anthraquinone dye Disperse Blue 2BLN by Aspergillus sp. XJ-2 CGMCC12963

“…[15][16][17] For instance, immobilized Aspergillus flavus was found to biodegrade anthraquinone dye Drimarene blue K2RL and convert the parent toxic dye into less toxic. 18 Nevertheless, Aspergillus niger SA1, Aspergillus fumigatus XC6 and Aspergillus fumigatus were reported to decolorize anthraquinone dyes only by bioadsorption, [19][20][21] which was far from the final step of decolorization. Therefore, the decolorization and degradation of anthraquinone dyes with specific contaminant-degrading fungi strains would be a promising alternative.…”

Ecofriendly decolorisation of Cr-complex dye Acid Black 172 by a newly isolated Pseudomonas sp. strain DY1

“…In recent years, a few investigations have focused on bioaccumulation of dyes by various growing biomass (Wang & Hu 2008;Das et al 2010). Compared to biosorption, bioaccumulation dyes from dye wastewater by growing biomass can avoid certain disadvantages of the traditional techniques, make the system simpler, and lower the operational cost (Xin et al 2010).…”
